PRNTERS LOCK-UP SQUARE.

Application iled December 12, 1923. Serial No. 680,214.

To all. iff/7mm if 71mg/ concern.'

le it known that l, ALBERT C. EVANS, a citizen ot the United States, anda resident et Butte, in the county ot Silverboiv and Siate of Montana,have invented certain new. andusetul improvements in Printers" Lock- UpSquares, or which the following is a .pecilieation My invention relatesgenerally to improvements .in devices for locking up type forms, andmore particularly to a device which is adapted for use in conjunctionwith a prini'ers chase having' no scale markings thereon, and itconsists in the combination, constructions and arrangements hereindescribed and claimed.

'lhe object oit the present invention .is to provide a device. ofthecharacter described which a'tlords facilities whereby it may be used inconjunction with a printers chase ot the character described to indicatethe position of a type form of any one of, a plurality of ysizes whenthe type torm is in centered rela-tion Within the chase and to indicateat` the saine time the number of pieces ot turniture which will berequired to secure the type torni in centered position Within the chase.I

A further object o't the invention is to provide a device oft thecharacter described which is light in Weight, economical to manufactureand conveniently and readily applicable to a printers chase for thepurpose set out in the foregoing.

Other objects and advantages will be apparent trom the followingdescription considered in conjunction with the accompanying drawings, iuwhich:

liigure is a` plan view, showing an enibodiment ol the invention inposition tor use on a printers chase, the latter being shoivndiagrammatically; and,

Figure 2 is a side elevation ci the chase with an embodiment ot theinvention thereon.

As is vvell known, considerable ditiiculty ordinarily is encountered andconsiderable time is consumed in ascertaining the centered position ofta type torni Within a printers chase having no scale markings thereonsince measuring operations are-necessary to determine the centeredposition ot the vtype iform and to also determine the number ot piecesot furniture which Will be required to secure the type torni Within thechase. To obviate the necessity of making any measurements-in pl acing atype form ot any one ot a plurality ot sizes Within a chase of thecharacter described, l provide); a device which l term a printers squareand which will. be so referred to hereina'ter.

As is ivell known, at the present time there are in use thousands oit'cha-ses made or cast iron which are not susceptible or" having picamarkings placed upon them, and it is intended by the manufacture of thissquare, to supply this need.

The printers square comprises a right angular body, indicated generallyat l, and consisting ot. bar like-members 2 and l, respectively. Theinner edges of the bar like members and lie in planes extending at rightangles to each other. rlie upper faces oi the bar-like members 2 and lprelerably are flat and lie in the same plane. The lower taces ot thebar-like members and 3 likewise are flat and lie in the same plane. TheImembers 2 and 3 respectively are of such length that the inner edge ot one oit these members, in this instance the member 2, will coincide withlength with the irmer edge ot the transverse member ot the printerschase 4e, and the inner edge oit the member 8 Will coincide in length`with the inner edge et a longitudinal member ot the chase 4 when thebody l is placed upon the chase et vvith the member 2 disposed upon thea't'oren'ientioned transverse member ot the chase and the member 3disposed upon the longitudinal member of the. chase.

'the member 3 is provided with a scale extending on the upper 'facethereof along` the inner edge ot' such member, the scale includinggraduations spaced apart to indicate picas. rlhe values o't thegraduatioas ot' the scale 5 increase in value. trom the outer end ot themember 3 and 'from a line extending trai'isverse y oit the member 3 inthe plane of the inner edge ot the member 2 toward a line Which extendstransversely to the member 3 midway of the length oit the inner edge ofthe member 3, such transverse median line being indicated at. (3.

In a like manner, the member 2 is provided With a scale indicated at 7,consisting oi spaced apart graduations on the upper tace ot' the member2 along the inner edge oj the, latter, the graduations oit the scaleindicating picas, and increasing in value from the outer end ot themember and 'from a line extending transversely ot the member 2 in theplane o't the inner edge o l the member 3 to a transverse line orgradlli) lll)
